Description

Technical Field

[0001] This application relates to the field of electrical components, and in particular to a wiring structure and switch. Background Technology

[0002] A switch is an electrical component used to control the on / off state of a circuit or to switch the current path. It is widely used in power systems, electronic equipment, and automation control. Wiring structures are used to connect power sources, switches, loads (such as lamps and motors), and other components into a complete circuit.

[0003] In the prior art, when external wires are connected to the wiring structure in a switch, the wiring depth may be insufficient, or the connection between the wire and the wiring structure may be unreliable, which may cause the external wire to come loose, thus affecting the normal use of the switch. Utility Model Content

[0004] To improve the stability of the connection between the wire and the switch, this application provides a wiring structure and a switch.

[0005] Firstly, the wiring structure provided in this application adopts the following technical solution:

[0006] A wiring structure includes a base, a circuit board mounted inside the base, a conductive sheet mounted on the circuit board, and a terminal block connected to the conductive sheet. The conductive sheet includes a plug-in end and a connecting part. The plug-in end is fixedly connected to the lower end of the connecting part. Two pins are fixedly connected to the end of the connecting part opposite to the plug-in end. The circuit board has positioning holes for pin insertion. The terminal block includes a wire sleeve and a fastener. The inner wall of the wire sleeve is connected to the outer wall of the plug-in end. The fastener is threaded to one side of the inner wall of the wire sleeve and is used to fix the wire.

[0007] By adopting the above technical solution, firstly, precise positioning is achieved by inserting the pins of the conductive sheet into the positioning holes of the circuit board, which improves the installation efficiency of the conductive sheet and ensures the stability of the connection between the conductive sheet and the circuit board, preventing the plug-in end from shifting and ensuring the stability of the electrical connection; secondly, by connecting the terminal block to the plug-in end and using fasteners to press the wire, the contact area and mechanical strength can be increased, preventing loosening.

[0008] Optionally, the end of the connecting part away from the plug-in end is fixedly connected to two limiting parts, and the two limiting parts face the wiring tube.

[0009] By adopting the above technical solution, when one side of the connector tube abuts against one side of the limiting plate, not only is misalignment of the connector tube reduced during use, but direct contact between the connector tube and the circuit board can also be prevented, thereby improving the service life of the circuit board.

[0010] Optionally, an anti-slip groove is provided on one side of the plug-in terminal, and the anti-slip groove is used to increase the contact area between the wire and the plug-in terminal.

[0011] By adopting the above technical solution, the anti-slip groove can increase the friction and contact area between the wire and the conductive sheet, reduce poor contact caused by vibration or pulling, and reduce the occurrence of wire falling off.

[0012] Optionally, the length of the junction box is 5mm to 10.5mm, and the length of the plug end is longer than the junction box.

[0013] By adopting the above technical solution, the increased length of the junction box can increase the insertion depth and fastening space of the wire, thereby increasing the contact area between the wire and the junction box and conductive sheet, and thus improving the connection reliability.

[0014] Optionally, one side of the base has a through hole communicating with the wiring sleeve, and the other side of the base has a positioning groove for fasteners to pass through.

[0015] By adopting the above technical solution, the design of the base through hole and positioning groove facilitates the alignment and installation of the junction box and fasteners, simplifies the assembly process, avoids structural interference, and makes it easy for people to insert one end of the wire into the junction box.

[0016] Secondly, the switch provided in this application adopts the following technical solution:

[0017] A switch includes a wiring structure and a touch unit mounted on one side of a circuit board. The outer side of the touch unit is fixedly connected to a latching member for hooking onto the inner wall of a base, and the inner side of one end of the latching member is used to hook onto the corner of the circuit board.

[0018] By adopting the above technical solution, the circuit board is fixed to the touch power supply by a snap fastener, and the touch unit is fixed to the base by a snap fastener. No additional soldering or screws are required, which facilitates disassembly and maintenance. Users can control the circuit's on / off state or adjustment (such as dimming or speed adjustment) by touching the panel of the touch unit (such as pressing or sliding).

[0019] Optionally, a fixing frame is fixedly connected to one side of the base, and the fixing frame is sleeved on the outside of the buckle.

[0020] By adopting the above technical solution, the fixing frame can not only protect the fasteners from external damage, but also shield electromagnetic interference and improve the service life of the switch.

[0021] Optionally, a panel is connected to one side of the fixed frame, and the panel has an opening slot for inserting one end of the touch unit.

[0022] By adopting the above technical solution, the panel opening slot is precisely matched with the touch unit, which can improve the overall aesthetics and safety of the switch and enhance the protection of the touch unit.

[0023] In summary, this application has the following beneficial effects:

[0024] 1. This application can achieve precise connection between conductive sheet and circuit board, improve structural installation efficiency, and increase the insertion depth and contact area of ​​wire through connecting cylinder and plug end, which can effectively prevent loosening and poor electrical contact.

[0025] 2. In this application, the touch unit can be quickly fixed to the base and circuit board through the snap-fit ​​component. Combined with the protective design of the fixing frame and panel, it simplifies assembly and maintenance while improving the anti-interference ability, aesthetics and service life of the switch.

[0033] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0034] This application discloses a wiring structure and a switch.

[0035] Reference Figure 1, Figure 2 The wiring structure includes a base 1 and a circuit board 2 mounted inside the base 1. Multiple sets of conductive plates 3 are provided on one side of the circuit board 2 for power conduction; each conductive plate 3 is equipped with a terminal 4 on its outer side, the terminal consisting of a terminal sleeve 41 and a threaded fastener 42. The side wall of the base 1 housing has a through hole 11 and a positioning groove 12: the power supply wire passes through the through hole 11 into the terminal sleeve 41, and the positioning groove 12 guides the fastener 42 to screw into the inner wall of the terminal sleeve 41 to press the wire. In use, first, the conductive plates 3 and terminal 4 are installed on the circuit board 2, and then the circuit board 2 is installed inside the base 1; then, the insulation layer at one end of the wire is peeled off, and the wire is inserted into the terminal sleeve 41 to contact the conductive plate 3; finally, the fastener 42 is tightened to fix the wire inside the terminal sleeve 41, completing the connection.

[0036] refer to Figure 3 , Figure 6 Each conductive sheet 3 includes a plug-in end 31, a connecting portion 32, and two pins 33. The connecting portion 32 is formed by bending the conductive sheet 3 along one end of the plug-in end 31, which is used for contact of the exposed part of the wire. Both pins 33 are formed by bending both ends of the connecting portion 32, and the orientation of the two pins 33 is opposite to that of the plug-in end 31. The circuit board 2 has multiple positioning holes 21 for inserting the pins 33. During installation, firstly, the conductive sheet 3 is moved to insert the two pins 33 into the positioning holes 21 until one side of the connecting portion 32 is in contact with the circuit board 2; then, the pins 33 are firmly bonded to the circuit board 2 pads by soldering (such as wave soldering or manual soldering) to prevent loosening.

[0037] refer to Figure 3 , Figure 4 and Figure 5 The junction box 41 is an integral cylindrical structure formed by bending a metal part. The inner wall of the junction box 41 is connected to the outer wall of the plug-in end 31, which improves the portability and efficiency of the junction box 41 installation. The length of the junction box 41 is 5mm to 10.5mm, and the length of the plug-in end 31 is longer than that of the junction box 41, which increases the insertion depth of the wire and improves the fixing effect of the wire. Two limiting parts 34 are provided between the junction box 41 and the connecting part 32. The limiting parts 34 are formed by bending the end of the connecting part 32 away from the plug-in end 31, and the two limiting parts face the junction box 41 to limit the position of the junction box 41 and maintain a certain gap between it and the circuit board 2. An anti-slip groove 311 is provided on one side of the plug-in end 31. The anti-slip groove 311 is composed of multiple V-shaped grooves to increase the contact area between the wire and the plug-in end 31.

[0038] During installation, firstly, the connector 41 is fitted onto the outside of the plug-in end 31. Then, the connector 41 is pushed until one side of it abuts against one side of the two limiting parts 34. Next, the end of the wire with its insulation stripped is inserted into the connector 41 until that end contacts the connecting part 32. Finally, the fastener 42 is tightened until one end contacts the wire, and the wire is pushed to fit snugly against the plug-in end 31, completing the wire fixing process.

[0039] Reference object 1 Figure 2 The switch includes a base 1, a fixing frame 7 fixedly mounted on one side of the base 1, a panel 8 mounted on one side of the fixing frame 7, and a touch unit 5 mounted inside the panel 8. In this application, the fixing frame 7 is a metal plate; in other embodiments, the fixing frame 7 can also be a plastic plate, composite plate, or other materials. The fixing frame 7 is used to improve the stability of the connection between the panel 8 and the base 1, and also to improve the stability of the connection between the base 1 and the junction box. The panel 8 has an opening groove 9 in the middle that fits against the outer wall of the touch unit 5, which improves the effect on the touch unit 5 and enhances the aesthetics of the switch. The touch unit 5 mainly consists of a touch panel, a response element, and a circuit connector. A circuit socket for inserting the circuit connector is fixedly connected to one side of the circuit board 2 to ensure the stability of the electrical connection between the touch unit 5 and the circuit board 2. When the touch panel is slid or pressed, the response element directs the signal from the circuit connector to the circuit board 2, thereby controlling the on / off or adjustment of the circuit.

[0040] refer to Figure 2 A latching member 6 is fixedly connected to the outer wall of the touch unit 5. Both the outer wall of one end of the latching member 6 and the inner wall of the other end are fixedly connected with buckles. The buckle on the outer wall of one end can hook into a slot on the inner wall of the base 1 to fix the touch unit 5 inside the base 1. The buckle on the inner wall of the other end can hook into the corner of the circuit board 2, fixing the circuit board 2 to one side of the touch unit 5 and ensuring the stability of the connection between the circuit board 2 and the touch unit 5.

[0041] The implementation principle of the wiring structure and switch in this application embodiment is as follows: In use, firstly, insert the two pins 33 of the conductive sheet 3 into the positioning hole 21 of the circuit board 2 until one side of the connecting part 32 is in contact with the circuit board 2. At this time, solder the pins 33 onto the circuit board 2 to fix the conductive sheet 3. Secondly, fit the wiring tube 41 onto the outside of the plug end 31 and push the wiring tube 41 until one side is in contact with one side of the limiting part 34 to complete the installation of the wiring tube 41. Thirdly, insert the plug on one side of the circuit board 2 into the outside of the plug of the touch unit 5, use the fastener 6 to fix the position of the circuit board 2, and then move the touch unit 5 to insert the fastener 6 through the fixing block into the base. Inside the base 1, the buckle of the clip 6 hooks into the slot inside the base 1, fixing the touch unit 5, circuit board 2, conductive sheet 3 and wiring terminal 4 inside the base 1; in the fifth step, move the panel 8, and fit its internal opening slot 9 onto the outside of the touch panel of the touch unit 5, and then fix the panel 8 on the fixing frame 7 to complete the assembly of the switch; finally, peel off the insulation layer of one end of the wire and insert it into the inside of the wiring tube 41 along the through hole 11 until the wire touches one side of the connecting part 32. At this time, use a tool to screw the fastener 42 through the positioning slot 12 into the inside of the wiring tube 41 and press one end of the wire so that the wire fits with the anti-slip groove 311 on the plug end 31 to complete the connection between the cable and the switch.
